Get raw bytes when reading DataMatrix format #41

Open kaciula opened 1 year ago

kaciula commented 1 year ago

I am reading a DataMatrix file and I need the exact raw bytes because the data stored in the DataMatrix is data compressed with zip and any sort of encoding messes up some of the bytes and the data cannot be read. I would need a Uint8List with the raw bytes.

Can you help?

Hi @kaciula

I added an 'rawBytes' array in scan result. Please update to v0.8.4 and check if it works as you need.

Thanks.

@khoren93 It works great! Thank you very much. Really appreciated.

@khoren93 I've only now tested on iOS and the raw bytes are completely different than they should be.

On Android it works perfectly. And I'm using the same image to test for both platforms.

Looking closer at the raw bytes, it seems the first 18 bytes are wrong on iOS and then the rest of the bytes are OK. Maybe it helps to track down the issue.

I'm also adding the DataMatrix image for testing purposes.

Hi @kaciula and @khoren93

I tried to read a barcode from iPhone but when the camera is scanning an error occurred "flutter: type 'ArgumentError' is not a subtype of type 'Code' in type cast". Even when uploading from gallery it is showing same error. Is there any fix. If so, kindly please do share.
